virtio: call virtio device reset method for reset
It refers to the implementation of the Cloud-hypervisor commit: - vm-virtio: Reset underlying device on driver request If the driver triggers a reset by writing zero into the status register then reset the underlying device if supported. A device reset also requires resetting various aspects of the queue. The reset method of a virtio device might return false if it is failed to reset the device or it is not implemented. In this case, we don't reset the queues. Otherwise the queues will also be reset together with a successful device reset.
